Title: Ink jet recorder
Inventor: YANO MASARU
IPC: B41J2/18
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To end cleaning operation in a short time while eliminating waste of ink and to prevent a bubble from being admixed to ink at the time of replacing an ink cartridge by jetting ink, at first, from a head part for jetting an ink droplet of large diameter and then jetting ink from a head for jetting an ink droplet of small diameter. SOLUTION: First and second head parts 26, 28 have cavities 38, 40 elongating in the facing direction of the head parts 26, 28 in parallel with each other. The cavity 38 of the head part 26 is set longer than the cavity 40 of the head part 28 in order to increase the ink containing quantity. Furthermore, a nozzle 50 of the first head part 26 has a larger diameter than a nozzle 52 of the second head part 28. Consequently, no ink is jetted from the first head part having a nozzle for jetting an ink droplet of large diameter when ink is jetted from the second head part having a nozzle for jetting an ink droplet of small diameter and thereby the ink is not wasted. Furthermore, bubbles mixed into the ink at the time of replacing a cartridge can be removed surely.

Abstract: PROBLEM TO BE SOLVED: To supply a generator with heat from the arm without lowering temperature by arranging inside a back lid a heat collector plate formed of a material having higher heat conductivity than the back lid and bringing a heat receiver of a generator into contact with a heat collector plate. SOLUTION: The heat collector plate 7 formed of a material such as aluminum, copper, etc., is coupled and fixed to a contact member 5A with a high heat conductivity on the inner surface (movement 1 side surface) of a back lid 5 formed with metal such as Ti, Ti alloy, stainless steel, etc., having a relatively low heat conductivity. Then, a heat reception part 6a of a thermoelectric type generator 6 is contacted to a heat collector plate 7 and a radiation part 6b is fixed to the heat conduction part 3a of a radiation upper shell 3 via a heat conduction plate 8.  Since the heat collector plate 7 forms a part in contact with the heat reception part 6a in a thick part 7a, heat tends to stagnate to maintain the temperature high, the heat transmitted from the arm to the back lid 5 is effectively collected inner direction and conducted to the heat reception part 6a side as maintained at a high temperature.

Title: Tooth brush
Inventor: TOKUSHO MITSUMASA
IPC: A61C17/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To suppress the moving width of bristle tips to a prescribed value and to avoid damaging the dental neck by providing the bristle tip fixing part of a tooth brush with a stopper and providing a grip part with a notched part. SOLUTION: This tooth brush 5 is so formed that the movement of the hand is transmitted to the bristle tip fixing part 4 of the tooth brush 5 when a stopper 3 disposed in the grip part 1 is moved to the end of the notched part 4 for sliding by the resistance of the bristle tip at the time of polishing in order to allow the bristle tip fixing part 1 and grip part 2 of the tooth brush 5 to move smoothly. Then, the moving width of the hand is decreased by as much as the width of the notched part 4 for sliding and is made into the moving width of the bristle tip fixing part 1 of the tooth brush 5. Consequently, the moving width of the hand is made smaller by as much as the width of the notched part 4 for sliding.  Since the bristle tip fixing part 1 and grip part 2 of the tooth brush 5 slide, the moving width of the hand decreases by as much as sliding and is transmitted to the bristle tips and, therefore, the moving width of the bristle tips considered to be optimum at the time of polishing may be easily attained at 1 to 2 mm.

Filed: 1988-12-22
Abstract: PURPOSE:To obtain a copy having satisfactory gradation by using a toner consisting of a carrier and a combination of two kinds of toner components having each specified property. CONSTITUTION:The developer consists of a carrier and a combination of two kinds of toner components(toner A, and toner B). The toner A consists of particles having a small average particle size so small as 2-4mum, but high chargeability as high as 20-30muc/g. Accordingly, the toner A reaches quickly a latent image part during development, thus contributes mainly to form picture images of medium contrast. On one hand, the toner B has a large average particle size as large as 8-12mum but the chargeability is so low as 5-10muc/g. Thus, the toner B contributes mainly to the formation of picture images of solid part. Thus, a distinct copy having satisfactory gradation is obtd.
